Product Details

Interlux Watertite Epoxy Filler YAV135 is a two-part, easy to use, fast drying epoxy compound for filling holes and repairing scratches in gelcoat and fiberglass. Watertite YAV135 is strongly recommended for filling gelcoat blisters below the waterline and for use with the Interprotect Epoxy Barrier System.

Info & Guides

Interlux Watertite YAV135 is an excellent fairing compound due to its unique two-phase cure, which gives a long easy-to-sand window. Watertite can be applied to a thickness of 3/4" without sagging and its superior spreadability makes it an ideal glazing compound for filling small nicks and scratches.

What is Gelcoat Blistering?

Osmosis is caused by a chemical reaction between water and unreacted substances remaining in the manufactured hull. Water breaches the exterior gelcoat and reacts with the chemical components creating acidic substances. These substances create pressure behind the gelcoat which causes blisters and eventually cracking. Once the gelcoat is breached in this manner, the underlying laminate is capable of absorbing water like a sponge.

Use the Interlux Interprotect system to treat and help prevent this insidious problem.

Excellent filler

I have used this many times on repair, restoration and re-finish of a wood boat. It goes on very smooth and clings to vertical surfaces very well. I have never had any problems with curing, cure times or getting hard. It is not difficult to sand, I usually use a 100 grit on electric sander for 1st sanding and then finer paper to achieve a nice surface. I highly recommend this.

I made repairs to gelcoat and a few blisters on a 1972 Venture 2-24 sailboat. I mixed as per instructions and it took longer to dry than I expected(overnight), however when it dried it sanded well and and faired out well. It does take some elbow grease to sand so don't over fill. Wear latex gloves as it can be messy and difficult to get off your hands. Taking a long time to set up can be a blessing as it gives you time to work with it and smooth it out without it gumming up to soon. Mix small amount because a little goes a long way. Over all I was very satisfied with the product and the Jamestown Tech's that I spoke to on the phone. If you own a boat of any kind you need to know Jamestown Dist. Everyone I spoke with was very professional and very familiar with the products they sell.

Excellent filler / fairing compound.

Interlux watertite is a great fairing compound for finish and detail fairing. Does not develop pin holes and goes on very smooth and light with a plastic spreader. Sands out nicely as well.

I use this product for filling and fairing. It goes on smooth and cures quickly. Can be sanded the same day it is applied. The cured epoxy is very hard and strong, however sanding is more difficult than common boat building epoxy. So close attention to getting a smooth initial application is helpful. Can be easily mixed in small batches. One component is blue, the other is white. The colors mix to a light blue, which is very helpful to indicate the components are well mixed. I keep the batches sized for the immediate task, mixing additional batches as needed.

shrinks really bad at least 50 percent

I used this product to fair a steel keel. I would not say it was totally bad and finished out very nicely. But took three applications to fair out smoothly due to shrinking

First time using Epoxy filler

11 years ago

I found the product to be very easy to mix and apply. I suggest wearing disposable plastic gloves as working upside down can get messy. The product did not set too fast but then again was able to be sanded in just a few hours. I have not put the baot in the water yet but feel confident this product will hold up as it is very tough stuff once it completely dries.

Repair/build, almost anything.

It's great to fix holes, and imperfections in whatever your working on. Great for a skim coat before painting. Repair cracks in water jackets, manifolds, anything that leaks. Frozen, busted engine parts. Loose bolt holes. Any loose fit, fills gaps well. Sticks to anything, and paint sticks to it well, great for a primer skim coat on bottom of boat, makes it strong, and water tight. Fills in holes, mistakes. etc..It costs a lot, but you won't be sorry.

Q: Do I need to use an epoxy resin first to seal any exposed fiberglass and can I embed new fiberglass mat with this product?

6 years ago

6 Answers

A: This product is just a filler, if you need to do structural or fiberglass repairs, use the appropriate epoxy system and cloth for the task. Glass matt is not necessarily the right fiberglass material to use for epoxy as it does not have styrene to break down the binder and wet out as easily.
